BACKGROUND

With the development of data storage and protection technologies, data protection systems suitable for a wide variety of data storage environments have been developed. Protected data (also referred to as assets) may include data from multiple components in a data storage environment, and therefore, when it is necessary to export a log of a target asset in a complex environment, the required time and the size of the log are difficult to estimate. Therefore, among existing data protection products, there is no data protection product that can provide functions for predicting the time for exporting a log and the size of the log file. Thus, there is an urgent need for a method that can accurately estimate the export time and the exported file size while exporting a log.

DETAILED DESCRIPTION

The embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the drawings show some embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms, and should not be explained as being limited to the embodiments stated herein. Instead, these embodiments are provided for understanding the present disclosure more thoroughly and completely. It should be understood that the accompanying drawings and embodiments of the present disclosure are for illustrative purposes only, and are not intended to limit the protection scope of the present disclosure.

In the description of embodiments of the present disclosure, the term “include” and similar terms thereof should be understood as open-ended inclusion, i.e., “including but not limited to.” The term “based on” should be understood as “based at least in part on.” The term “an embodiment” or “the embodiment” should be understood as “at least one embodiment.” The terms “first,” “second,” and the like may refer to different or identical objects. Other explicit and implicit definitions may also be included below.

In addition, all specific numerical values herein are examples, which are provided only to aid understanding, and are not intended to limit the scope.

The inventors note that in data protection products, the time consumption for exporting a log is highly variable due to the complexity of storage devices of data (also referred to as assets, no distinction being made between data and assets hereinafter), the diversity of users, differences in computing systems that allow data protection products, differences in usage environments (e.g., network speed), and so on. This brings bad user experience to users, and makes them unable to make advance arrangements, thus affecting their work.

In view of this, the method of the present disclosure provides a method for exporting a log. The method utilizes various factors associated with log export, each of which may individually or in combination affect the time consumed by exporting a log. Therefore, by taking these factors into account and using a reasonable algorithm, it is possible to accurately estimate the time required to export a log.

FIG. 1 illustrates a schematic diagram of example environment 100 in which embodiments of the present disclosure can be implemented.

In environment 100, computing resource 101 (e.g., a computing system or a server) has data protection product 102 installed thereon. Through a network, data protection product 102 is connected to a user. Assets protected by the data protection product may be stored in multiple storage devices 103-1, 103-2, 103-N (individually or collectively referred to as storage device 103). Storage device 103 is connected to computing resource 101.

FIG. 2 schematically illustrates a flow chart of method 200 for exporting a log according to an example implementation of the present disclosure.

At block 202, a first set of attributes including a target asset among assets protected by a data protection product, a second set of attributes of target tasks executed on the target asset, and a third set of attributes of a computing resource running the data protection product are acquired.

In some embodiments, the first set of attributes may include the number of Structured Query Language (SQL) assets, the number of file system assets, the number of virtual machine assets, the number of network attached storage (NAS) assets, the number of SAP HANA assets, and the number of Kubernetes K8S assets. The first set of attributes may also include the number of data protection policies in the entire data protection system and the number of data protection phases in the entire data protection system.

In some embodiments, the second set of attributes may include the number of target tasks, sizes of the assets (e.g., in bytes), data sizes of compressed assets, data sizes of transmitted assets, type of the target tasks, the frequency at which the target tasks are executed, subtasks of the target tasks, the number of times of successful execution of the subtasks, the number of times of failed execution of the subtasks, and the number of canceled subtasks.

In some embodiments, the third set of attributes may include attributes of the computing resource running the data protection product, for example, hardware attributes. For example, the number of cores of the CPU, the primary frequency of the cores, the IO access speed of a storage device, the PCIE type, the network bandwidth, the network delay, and so on.

At block 204, an export time consumed to export a log of the target asset is determined based on the first set of attributes, the second set of attributes, and the third set of attributes.

In some embodiments, the first set of attributes, the second set of attributes, and the third set of attributes may be input to a machine learning model, and the machine learning model may accurately determine how much time will be consumed to export the log based on these input attributes.

It will be understood that the attributes that may be included in the first set of attributes, the second set of attributes, and the third set of attributes are all closely related to the time required to export the log. Thus, after considering these important and closely related attributes, a reasonably trained machine learning model is utilized, so that the determined time required to export the log is relatively accurate.

In some embodiments, the method may further include determining the export time consumed to export the log of the target asset based on a fourth set of attributes including a type of a customer owning the target asset, a time at which the export of the log occurs, and a time length of continuous operation of the data protection product. That is, the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes may all be input into the machine learning model, and the export time consumed to export the log of the target asset may be determined using the machine learning model.

In some embodiments, the time at which the export of the log occurs may be accurate to a day (e.g., one day of the week) or to a finer granularity (one hour of the day). For example, the operation of exporting the log is performed in the morning of Wednesday (more specifically, at 10:00 am).

In some embodiments, the method may further include determining a size of the log of the target asset using the machine learning model.

In some embodiments, the type of the asset may include at least Structured Query Language (SQL) asset, file system asset, virtual machine asset, network attached storage (NAS) asset, SAP HANA asset, and Kubernetes K8S asset.

In some embodiments, the method may further include exporting the log of the target asset during the export time.

In some embodiments, the machine learning model is a multilayer perceptron, and the multilayer perceptron may include at least a first hidden layer, a second hidden layer, and a third hidden layer, and a first number of nodes of the first hidden layer is determined by: selecting a specified number of attributes from the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes, and determining the first number of nodes as the smallest positive integer power of 2 greater than or equal to the specified number.

In some embodiments, at least ten attributes are selected from the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes; values that satisfy the following conditions are determined: (i) being greater than or equal to the number of the selected attributes, and (ii) being a positive integer power of 2; and the minimum value satisfying the conditions is determined as the first number of nodes. The machine learning model used in the present disclosure will be described in detail below with reference to FIG. 3 .

FIG. 3 schematically illustrates a schematic diagram of machine learning model 300 according to an example implementation of the present disclosure.

As shown in the figure, this machine learning model 300 may include first module 301 and second module 302. The first module is configured to determine the time required to export the log. The second module is configured to determine the size of the exported log.

The structures of first model 301 and second module 302 may be the same or different. In FIG. 3 , first module 301 and second module 302 are shown with the same structure, both being a fully connected structure. The structure includes an input layer, a hidden layer, and an output layer, where the number of nodes in the input layer is the same as the sum of the attributes in the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes. Here, the attributes may also be referred to as features, and no distinction will be made between attributes and features hereinafter. The output layer has a node for outputting the time required to export the log or the size of the exported log.

In some embodiments, there may be 3 hidden layers. The number of nodes in the first hidden layer needs to satisfy the following equation:

${h1_{\min}} = {\min\limits_{x}\left( {{x \geq {n{and}x}} = {{2^{t}t} \in N^{+}}} \right)}$

where x denotes the number of attributes selected from the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes, t denotes a positive integer, h1_(min) denotes the minimum number of the first hidden layers, and min denotes the operation to find the minimum value.

In some embodiments, a second number of nodes of the second hidden layer is greater than or equal to the first number of nodes, and a third number of nodes of the third hidden layer is greater than or equal to the first number of nodes.

FIG. 4 schematically illustrates a schematic diagram of a hidden layer of a machine learning model according to an example implementation of the present disclosure.

As shown in the figure, by way of example only, first hidden layer 401 may include 32 nodes, second hidden layer 402 may include 64 nodes, and third hidden layer 403 may include 128 nodes.

In training the machine learning model, the machine learning model may be trained using the following training data which needs to satisfy the following condition: for a portion of the protected assets, at least ten attributes are selected from the attributes in the first set of attributes to the fourth set of attributes. The number of the portion of assets is determined in a certain proportion according to the number of total assets.

It can be understood that the machine learning model trained in this way adequately learns hidden relationships between the various attributes and the time to export the log and has the capacity to generalize. Thus, in the inference phase, it is possible to make a good determination (e.g., prediction) of the time to export the log for the target asset as well as the size of the log.

FIG. 5 schematically illustrates a block diagram of an apparatus for exporting a log according to an example implementation of the present disclosure.

Set acquisition module 502 is configured to acquire a first set of attributes indicating a target asset among assets protected by a data protection product, a second set of attributes indicating target tasks executed on the target asset, and a third set of attributes indicating a computing resource running the data protection product.

Log export module 504 is configured to determine an export time consumed to export a log of the target asset based on the first set of attributes, the second set of attributes, and the third set of attributes.

In some embodiments, set acquisition module 502 may further be configured to determine the export time based on the first set of attributes, the second set of attributes, the third set of attributes, and a fourth set of attributes, wherein the fourth set of attributes includes a type of a customer owning the target asset, a time at which the export of the log occurs, and a time length of continuous operation of the data protection product.

In some embodiments, determining an export time consumed to export a log of the target asset comprises determining the export time using a machine learning model, wherein the machine learning model is a multilayer perceptron that comprises a first hidden layer, a second hidden layer, and a third hidden layer, and a first number of nodes of the first hidden layer is determined by: selecting a specified number based on the number of all attributes of the first set of attributes, the second set of attributes, the third set of attributes, and the fourth set of attributes; and determining the first number of nodes as the smallest positive integer power of 2 greater than or equal to the specified number.

In some embodiments, a second number of nodes of the second hidden layer may be greater than or equal to the first number of nodes, and a third number of nodes of the third hidden layer may be greater than or equal to the first number of nodes.

In some embodiments, log export module 504 may further be configured to determine a size of the log of the target asset using the machine learning model.

In some embodiments, the second set of attributes includes the number of the target tasks, types of the target tasks, the frequency at which the target tasks are executed, the number of subtasks of the target tasks, the number of successful subtasks, the number of failed subtasks, and the number of canceled subtasks.

FIG. 6 schematically illustrates a flow chart of a method for training a machine learning model according to an example implementation of the present disclosure.

At block 610, some attributes are selected from a first set of attributes, a second set of attributes, a third set of attributes, and a fourth set of attributes, and the number of these attributes should be above a certain number (e.g., 10 to 13 attributes in total, and at least one attribute should be selected from each set of attributes). At this stage, these selected attributes are also referred to as features. The data obtained at this stage may be referred to as sample data.

At block 620, the selected features may be input into a machine learning model for training, and the training process may use a back propagation algorithm. When parameters of the machine learning model meet the requirements, the training process is ended.

At block 630, the machine learning model may be brought into an inference phase, in which test data is input to get a predicted result (i.e., predicted export time and log size) on the test data.

At block 640, if the error between the predicted result and the true result is large, the method proceeds to block 650. If the predicted result meets the requirement of accuracy, the method proceeds to block 660.

At block 650, the machine learning model is retrained with new training data (which may also include previously used sample data) and may be trained with more features.

At block 660, the machine learning model is deployed for real use by users.
